Slang, obscenities, casual speech, and everyday spoken language are all part of vernacular speech. While there is nothing whatsoever wrong with vernacular speech, it is considered too casual for academic writing.
Introduction
We don't compose essays for our English class the same way we communicate to our friends. The term "vernacular" describes our straightforward, common language. It's the language we use when we text our closest friend or when we speak informally to our siblings. Even slang and obscenities are part of the vernacular. So it stands to reason that the speech of a group of Princeton engineering professors conversing informally over lunch would sound very different from that of a bunch of young girls at a sleepover.
Vernacular examples in English
Here are some examples from America, the UK, and Australia:
American vernacular
grinder (New England) for sandwich
y’all (American south) for all of you or you all
down (West Coast) for ready for or OK with something
pop (Midwest) for soda
British vernacular
quid for money or cash
chin wag for long chat or discussion
Bob’s your uncle for everything is OK
jumper for sweater
Australian vernacular
avo for avocado
dunny for toilet
flat out for very busy
runners for sneakers or running shoes
Conclusion
Another particular language created to aid in communication is vernacular. Everyone speaks a different language, even physicians, lawyers, and movie buffs. My grandma would definitely give me a strange look if I said, "The fish rivered his flush to defeat my trips when I pushed all-in." My weekend poker companions would understand exactly what I meant if I mentioned that to them. You can also download our app from the playstore or visit our website.
